High Quality Content by WIKIPEDIA articles! A weather-related cancellation or delay is closure, cancellation, or delay of an institution, operation, or event as a result of inclement weather. Certain institutions, such as schools, are likely to close when bad weather, such as snow, flooding, tropical cyclones or extreme heat or cold impairs travel, causes power outages, or otherwise impedes public safety or makes opening the facility impossible or more difficult. Depending upon the local climate, the chances of a school or school system closing may vary. While some regions may close or delay schools when there is any question of safety, others located in areas where bad weather is a regular occurrence may remain open, as local people may be accustomed to travelling under such conditions.
